1. Triangle ABC has a 63.0degree angle at B, and side AC is 13.6 cm long. What is the diameter of the circle circumscribed about ABC?
2. And: Given any triangle ABC, with sides a, b, and c opposite angles A, B,
and C, respectively, what can be said about the three ratios a/sinA , b/sinB
, and c/sinC ? This result is known as the Law of Sines.
